# Grassroots
This web-based tool allows you to add your Ontario Vaccination Receipt as a pass into your Apple Wallet on iOS in a privacy-respecting way. It achieves this without sending your data to a server and instead only uses a hashed representation for the signing step.
Here is a [demo](https://www.youtube.com/watch?v=AIrG5Qbjptg)
# Quick start
* Go to [https://grassroots.vaccine-ontario.ca](https://grassroots.vaccine-ontario.ca)
* Click Ontario Health to download your vaccination receipt onto your iPhone (local storage)
* Select File, Browse, your-vaccine-receipt.pdf
* Add to the wallet
### Debug the web app
```sh
yarn install
yarn dev
```
### Run the Docker container
```sh
docker build . -t covidpass
docker run -t -i -p 3000:3000 covidpass
```
# FAQ
#### I do not want to trust a third party with my vaccination data, does this tool respect my privacy?
Processing of your data happens entirely in your mobile browser and only a hashed representation is sent to the server for the signing step.
#### How do I make sure that nobody can access my vaccination pass from the lock screen (iOS)?
Navigate to the "TouchID & Code" or "FaceID & Code" or just "Code" section in the Settings and switch the toggle to off for Wallet in the section "Allow access from the lock screen". Also see [this official guide](https://support.apple.com/guide/iphone/control-access-information-lock-screen-iph9a2a69136/ios) from Apple.
# Using your own Apple Developer Certificate (if you would like to fork this project and run it yourself)
## Get your certificate
* Sign into your [Apple Developer Account](https://developer.apple.com/account/)
* Go to Certificates, Identifiers and Profiles
* Register a new Pass Type Identifier under the Identifiers tab
* Create a new Pass Type ID Certificate under the Certificates tab
* Select your previously created Pass Type Identifier in the process
* Move your new certificate to the My Certificates tab in the keychain
* Export your certificate as a .p12 file
* Install node.js and download the [passkit-keys](https://github.com/walletpass/pass-js/blob/master/bin/passkit-keys) script
* Create a `keys` folder and put the .p12 file inside
* Run ./passkit-keys `<path to your keys folder>`
* You may have to type in the passphrase you defined during the export step
## Run the API locally
A description of how you can use your certificate locally with the API will be provided in the readme of the [CovidPass API](https://github.com/covidpass-org/CovidPassApiNet).
To connect the web app to your local server, you have to set the `API_BASE_URL` environment variable accordingly.
# Explanation of the process
The whole process of generating the pass file happens locally in your browser. For the signing step, only a hashed representation of your data is sent to the server.
First, the following steps happen locally in your browser:
* Validating the digital signature on the receipt from Ontario Health to ensure it's authentic
* Decoding your vaccination event data from the PDF file (e.g. date, type of vaccine, dose #, organization who administered it
* Assembling a pkpass file out of your data
* Generating a file containing hashes of the data stored in the pass file
* Sending only the file containing the hashes to the server
Second, the following steps happen on the server:
* Receiving and checking the hashes which were generated locally
* Signing the file containing the hashes
* Sending the signature back
Finally, the following steps happen locally in your browser:
* Assembling the signed pass file out of the incomplete file generated locally and the signature
* Saving the file on your device
# Credits
The idea for this web app originated from the [solution of an Austrian web developer](https://coronapass.fabianpimminger.com), which only works for Austrian certificates at the moment.
The main codebase is forked from [covidpass](https://github.com/covidpass-org/covidpass) and added Ontario specifcs.
